Abstract
(SB1175 · 103rd Legislature) Public utilities: electric utilities; distribution grid plans created by electric utilities; require. Amends sec. 6a of 1939 PA 3 (MCL 460.6a). Sponsor: Sen. Jeff Irwin (D) + 7 co-sponsors In committee: S Energy And Environment Latest action (2026-09-10): Referred To Committee On Energy And Environment
Why this matters
Distribution grid investment is one of the largest drivers of recent utility rate increases in Michigan, yet it has historically received less structured MPSC scrutiny than generation or transmission planning. A statutory requirement for utilities to file distribution grid plans would create a formal docket where regulators, intervenors, and ratepayers can examine reliability, capacity, and cost assumptions before those investments hit rate cases.
